Question 914039: I am trying to solve each system by graphing I would like to know if I am solving this correctly problem -5x+4y=-16
x+4y=8
-5_+_4y = 16
4 4 4
y=x12
y= -5x+8
4 4
Answer -3

You can put this solution on YOUR website!
I have no idea what you are showing as your steps.

You seem to indicate the system,
system%28-5x%2B4y=-16%2Cx%2B4y=8%29

How do you want graph? x and y intercepts? Slope and y-intercept?

4y=5x-16
y=%285%2F4%29x-4

4y=-x%2B8
y=-x%2F4%2B4

You can read the y-intercepts and the slopes.

graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C%285%2F4%29x-4%2C-x%2F4%2B4%29

Try this on graph PAPER and you may be able to read a satisfactorily accurate value for the intersection point.
